Yesterday's Featured Image highlighted boulders eroding out of a hill in the Anaxagoras crater impact melt pond. The opening image above highlights an impact melt flow located on the lunar far side at 23.99°N, 209.94°E. The impact melt flowed from its source crater through rubbley ejecta before it cooled. There are several lobes at the terminus of the flow; perhaps these lobes "broke out" when the surface of the flow cooled but the interior of the flow remained hot and could still flow. The farthest-reaching lobe extends for about 95 m past the large lobe. There are some small boulders, <10 m across, that are entrained in the impact melt, but most of blocks close by seem pushed or maneuvered there by the flow, much like a levee formed during a volcanic flow.
How much of the flow do you observe the full LROC NAC image and can you trace its path across the image?
